      the ovs interface by assigning a vlan tag and
      installing openflow rules as appropriate.
    - This change will reduce the live migration
      time for kernel ovs ports with hybrid plug false
      by creating the ovs port as part of plug before
      the migration starts.
    - This change adds the privsep decorator
      to delete_net_dev to account for it new usage
